I have a Sanyo Kantana mobile phone. It was compatable with TTR V1 but the Tom Tom support people tell me it is not compatable with V2. (go figure) I think it is compatable because when I try to connect my phone finds the TomTom Rider but it asks for a pin code. I have tried all the standards 1111,0000,5555, and last 4 digits of phone number. Any smart hacker out there who may be able to help???????
